About Me

Hello! I am Marvin O. Onen 

 

A Construction Project Management professional with nearly nine years of progressive experience delivering construction projects across Uganda's Roads & Buildings Infrastructure and Oil & Gas sectors, including over five years embedded in the Tilenga Upstream Facilities development, one of Uganda's most demanding, high-compliance project environments.

 

Across these engagements, I have contributed to and managed a combined project value exceeding USD 19.3M.

Areas of Expertise
Project Scheduling & Planning

Development and maintenance of integrated project schedules using MS Project and Primavera P6, from tender-stage work programmes to live baseline tracking across multiple concurrent projects. I define Work Breakdown Structures, build look-ahead and recovery programmes, and monitor planned versus actual progress, flagging deviations before they become delays.

Site Resource & Productivity Management

Coordination of materials, personnel, and equipment allocation, including fuel issuance tracking and plant productivity monitoring across active work fronts, ensuring optimal resource utilisation, accurate cost reconciliation, and uninterrupted progress against the project schedule.

Cost Rate Buildups & Pricing

Development of unit rates from first principles, quantity take-offs, and BOQ pricing for tenders and budget estimates. I build defensible, competitive pricing that reflects true labour, plant, and material costs, not guesswork, translating directly into accurate project budgets from day one.

Cost Control & Budgeting

End-to-end budget development, expenditure tracking, Cost Value Reconciliation (CVR), and variance management. I've built and monitored project budgets ranging from USD 100k to USD 8M+, comparing cost against value delivered and keeping stakeholders informed with timely corrective action.

Contract Administration

Preparation of Interim Payment Certificates (IPCs), Variation Orders, valuations, notices, and final account statements. I manage the paperwork that protects both programme and profit.

Tender Preparation

Development of Method Statements, Health, Safety & Environment Management Plans, Quality Management Plans, and BOQ pricing. I aim for submissions that don't just meet compliance, they win contracts.

Site Supervision & Project Management

Full-cycle project leadership from mobilisation to client handover. I coordinate multiple contractor and subcontractor work-fronts, resolving site challenges, resourcing, and sequencing work to keep programme and quality on track.

QH3SE Compliance

Management of Inspection & Test Plans (ITPs), Non-Conformance Reports (NCRs), Material Approval Reports (MARs), and Requests for Inspection (RFIs), alongside enforcement of safety protocols across active work fronts. I bring direct experience coordinating hold and witness points with client quality representatives, and have maintained a zero lost-time incident record across every project under my direct site leadership.
